Jetson Orin AGX not showing on display after running sudo apt dist-upgrade and rebooting following carolyuu response in the following forum. Indicator Led is turned on and the Orin is heating and the fan is not turning on with exception of a few seconds after powering up the orin
I’m not sure why the display output wouldn’t work; but have you tried connecting a USB cable to the serial interface and connecting via screen or another terminal app, per the initial setup instructions?
I have already tried using an usb-c and a micro-usb. When connected via Usb-C and running the dmesg | grep --color 'tty' there does not appear any new device. Using a micro-usb and following this tutorial i have acess to the UART ports but have no idea of how to begin the debug process.
Connect the micro usb port instead of the type C port.
The logs coming out from these two ports are different.
type C port does not give any log from UART. This is really a usb port which only gives kernel log, which is same as dmesg. This port can only work if your device boots into kernel. But if your system fails to boot into kernel, stuck somewhere in early bootloader, then type C won’t show anything.
Micro usb port is really based on UART. And it can dump the bootloader log. Thus, start from micro usb port instead of type C.
For example, only micro usb port can show below example log from the website.
I manage to connect an access the bootloader log from another computer via micro-usb connection. The orin printed all the bootloader logs anfd finally launch me a login request, after login in to the orin the following was printed on the terminal.
orin-desktop login: orin

I append the full bootloader logs in a txt formatt as I am unable to understand if any of the logs is abnormal
Yes, I use a DP to HDMI adapter cable, and then connect the monitor, the monitor only has a picture when it is just started, but after booting, the monitor shows no signal input.
I connected the adapter cable and HDMI cable to the PC, and the picture can be displayed normally, which means that there is no problem with the cable
Sorry, another clarification for this issue. Is this issue related to “sudo apt dist-upgrade”?
I mean, this post was filed by @Farideh and his issue happened after doing apt-dist-upgrade. Is this happened to you too? Or your monitor does not work from the beginning? I mean, even no need to run apt command and you can reproduce issue.
I’m sorry, as I was in a hurry, I saw that the description of this problem contained “can’t see the monitor”, so I asked for help under this problem, I actually asked a question myself, but no one responded me.
My problem is actually that after starting orin, the monitor has no signal. It does not execute similar commands
